Aluminium, zoo li nws cov hlau nplaum, tau siv dav hauv ntau thaj chaw ntawm kev lag luam. Kev tsim cov hlau los ntawm cov hlau no ib txwm xav tau, thiab nws tseem nyob li niaj hnub no.
Cov khoom yooj yim
Aluminium hlau yog cov khoom siv tau ntev uas muaj qhov ntev me me rau ntu ntu ntu ntu. Cov khoom siv hlau no muaj cov yam ntxwv hauv qab no:
- lub cev hnyav;
- yooj;
- lub zog;
- tiv taus ya raws;
- hnav tsis kam;
- kav ntev;
- tsis muaj zog ntawm cov khoom sib nqus;
- lom inertness;
- melting point 660 degrees Celsius.
Aluminium hlau, uas tau ua raws li GOST, muaj ntau qhov zoo thaum piv nrog lwm cov khoom lag luam zoo sib xws. Cov khoom siv muaj ntau yam thiab tiv taus xeb, yog li nws feem ntau siv thaum muaj kev sib cuag nrog dej yog qhov tsis yooj yim sua . Aluminium qiv nws tus kheej kom ua tau zoo thiab muaj kev nyab xeeb rau tib neeg kev noj qab haus huv. Cov xaim feem ntau ua tau raws li qhov yuav tsum tau ua ntawm Kev Pab Huv Huv thiab Kab Mob Sib Kis.
Kev zom cov hlau ntxig no tshwm sim yam tsis muaj teeb meem . Thaum tiv tauj nrog huab cua, cov yeeb yaj kiab oxide tshwm ntawm cov xaim, vim qhov khoom tsis xeb lossis tsis zoo nyob rau ntau xyoo. Cov khoom ntawm txhuas hlau ncaj qha cuam tshuam los ntawm lub xeev cov hlau, nrog rau cov txheej txheem tsim khoom.
Aluminium hlau pas nrig, uas muaj txoj kab uas hla ntawm 9 txog 14 hli, yog qhov tshwj xeeb los ntawm kev ntxiv dag zog thiab tiv taus cov khoom puas.
Kev tau txais tuaj yeem ua tiav hauv peb txoj hauv kev
- Dov yog ua raws li kev ua haujlwm nrog aluminium ingots . Cov txheej txheem tsim khoom tau ua tiav ntawm cov hlau xeb zeb, uas zoo li tshwj xeeb cov cuab yeej siv tshuab tshwj xeeb thiab muab nrog cov cua sov rauv.
- Kev nruam nruam raug txiav txim siab yog tias cov khoom siv tau nthuav tawm hauv daim ntawv ntawm cov hlau yaj . Txoj haujlwm no cuam tshuam nrog thauj cov kua ua kua rau hauv cov crystallizer. Muaj qhov txiav tawm hauv lub log tshwj xeeb tig, nws txias los ntawm cov dej loj. Thaum txav mus, crystallization ntawm cov hlau tshwm sim, uas tau xa mus rau cov ncej ntxig. Cov khoom tiav yog dov rau hauv spools thiab ntim rau hauv hnab polyethylene.
- Nias . Txoj kev tsim khoom no tau txiav txim siab muaj feem cuam tshuam hauv cov lag luam uas muaj hydraulic nias. Hauv qhov no, cov rhaub rhaub raug xa mus rau cov thawv ntim khoom. Cov khoom siv tau ua tiav siv lub siab ntawm lub punch, uas tau nruab nrog lub tshuab ntxhua khaub ncaws.
Txhawm rau kom txhuas hlau kom muaj qhov ua tau zoo thiab tus yam ntxwv zoo, cov tuam ntxhab ua cov txheej txheem ua ntej:
- deformed los ntawm txias - nyob rau hauv txoj kev no hom AD 1, AMg3, AMg5 tau ua;
- txias thiab hnub nyoog los ntawm txias - D1P, D16P, D18;
- raug rho tawm, uas ntxiv cov yas rau cov xaim;
- ua cov txheej txheem abrasive, uas pab tshem tawm cov burrs, puag ncig ntawm cov npoo hlau.
Aluminium hlau tau kos los ntawm cov pas hlau los ntawm kev kos duab. Txhawm rau ua qhov no, nqa ib daim ntawv ua haujlwm uas muaj txoj kab uas hla ntawm 7 txog 20 mm thiab rub nws nrog luag, uas muaj ob peb qhov.
Yog tias yuav tsum tau khaws lub sijhawm ntev, txheej txheej oxide saum npoo yog tso tawm los ntawm kev tso cov khoom hauv cov tshuaj sulfuric acid yaj.
Cov cheeb tsam ntawm kev siv
Ntev-ntev txhuas xov yog dav siv los ntawm cov neeg hauv ntau yam haujlwm ntawm lawv cov haujlwm. Nws yog qhov tsim nyog xaiv rau phau ntawv, arc, argon thiab tsis siv neeg vuam. Cov nqaws tsim tom qab vuam tuaj yeem tiv thaiv ib feem los ntawm kev xeb thiab deformation . Txawm hais tias nws qhov hnyav tsawg, cov khoom no yog lub zog zoo, yog li nws feem ntau siv hauv kev tsim kho, ntxiv rau hauv kev tsim cov nkoj, tsheb, dav hlau.
Aluminium hlau yog cov khoom siv tau ntau yam rau cov khawm ris . Nws yog qhov xav tau hauv kev tsim cov rooj tog, ntxiv rau cov khoom tseem ceeb xws li cov dej ntws, ntxaij, txuas, rivets. Ntiav tau pom nws daim ntawv thov hauv hluav taws xob engineering, kav hlau txais xov, hluav taws xob, kab xa hluav taws xob, kev sib txuas lus tau tsim los ntawm nws. Ib qho ntxiv, txhuas hlau yog qhov tseem ceeb hauv kev lag luam khoom noj.
Ntau yam kho vajtse tau tsim los ntawm cov hlau no, txawm tias siv laum, lub caij nplooj ntoo hlav thiab cov hluav taws xob muaj cov hlau no nyob hauv lawv cov muaj pes tsawg leeg. Cov xov xov thoob ntiaj teb no yog qhov tsis tseem ceeb hauv kev tsim khoom ntawm cov khoom siv rau kev lag luam tshuaj lom neeg thiab cov cuab yeej siv siab . Hlau xav tau hauv kev tsim cov khoom zoo nkauj, hniav nyiaj hniav kub thiab khoom plig. Aluminium xaim xaim yog suav tias yog daim duab kos duab niaj hnub no.
Hauv kev tsim toj roob hauv pes, koj tuaj yeem pom gazebos, rooj zaum thiab laj kab ua los ntawm cov khoom lag luam ntev. Cov khoom siv sib txuam muab kev pab ncaj qha hauv kev ua tiav ntawm cov phiaj xwm kev tshawb fawb tshiab.
Hom kev txheeb xyuas
Thaum lub sijhawm tsim cov hlau txhuas, cov tuam txhab nruj ua raws li qhov yuav tsum tau ua ntawm GOST. Nyob ntawm tus yam ntxwv ua haujlwm, cov khoom ntev no tuaj yeem nthuav tawm hauv ntau hom. Nws tau lees paub hauv cov kauj lossis cov kauj, qhov hnyav nyob ntawm qhov ntev thiab txoj kab uas hla ntawm xaim.
| Nominal txoj kab uas hla, hli | Qhov hnyav 1000 meters, kg |
| 6, 1654 | |
| 24, 662 | |
| 55, 488 | |
| 98, 646 | |
| 154, 13 | |
| 221, 95 | |
| 302, 1 |
Raws li qhov xwm txheej ntawm cov khoom siv, xaim yog:
- kub nias, tsis kho cua sov;
- annealed, muag muag;
- txias ua haujlwm;
- tawv ib txwm los yog muaj hnub nyoog dag.
Los ntawm cov tshuaj lom neeg muaj pes tsawg leeg
Nyob ntawm cov ntsiab lus ntawm cov khoom siv tshuaj, txhuas hlau tau muab faib ua hom hauv qab no:
- cov pa roj carbon tsawg (cov pa roj carbon ntau tsis ntau tshaj 0.25 feem pua);
- alloyed;
- alloyed heev;
- raws li tsev neeg hlau.
Los ntawm seem zoo
Hauv kev hla ntu ntu, txhuas hlau tuaj yeem yog:
- puag ncig, oval, xwmfab, duab plaub;
- trapezoidal, ntau yam zoo nkauj, segmental, duab puab;
- zeta, x-puab;
- nrog ib ntus, zoo li tus, tshwj xeeb profile.
Los ntawm hom nto
Cov hom hlau txhuas hauv qab no tuaj yeem pom ntawm cov khoom lag luam:
- polished;
- polished;
- etched;
- nrog cov xim hlau thiab tsis yog xim hlau txau;
- lub teeb thiab dub.
Vuam txhuas hlau yog siv thaum lub vuam siv hauv kev tsim kho, kev tsim kho tshuab. Ua tsaug rau kev siv cov khoom no, qib siab ntawm kev tsim khoom ntawm cov qauv tau pom. Cov khoom lag luam nrog AD1 hom yog tus yam ntxwv ua hluav taws xob zoo, tiv taus corrosion thiab ductility. Nws muaj cov khoom sib ntxiv xws li silicon, hlau thiab zinc.
Cov Lus Qhia Xaiv
Nws yog qhov tsim nyog xaiv ib qho txhuas vuam hlau nrog txhua lub luag haujlwm, muab nws cov muaj pes tsawg leeg. Qhov kev xaiv zoo tshaj plaws hauv rooj plaub no tau txiav txim siab ua cov khoom sib xyaw ua ke nrog cov tshuaj ntxiv thiab ntxiv rau. Cov xaim hluav taws xob yuav tsum nyob ze rau qhov sib xyaw ntawm cov nplaim yuav tsum tau welded, tsuas yog ua li no thiaj yuav ntseeg tau thiab ruaj khov. Cov kws tshaj lij pom zoo kom tsis quav ntsej cov tuab ntawm cov khoom, vim nws tuaj yeem nyuaj ua haujlwm nrog cov khoom tuab heev.
Cov ntsiab lus los saib xyuas thaum yuav khoom txhuas hlau:
- lub hom phiaj - feem ntau cov chaw tsim khoom qhia ntawm daim ntawv lo rau lub hom phiaj twg cov khoom tuaj yeem siv tau;
- txoj kab uas hla;
- footage nyob rau hauv ib pob;
- yaj kub;
- tsos - qhov khoom ntawm qhov khoom yuav tsum tsis txhob muaj cov xeb xeb, cov xim ntawm cov xim thiab cov khoom siv ua kua, nrog rau roj.
Npav
Thaum tsim cov hlau, cov chaw tsim khoom siv ob qho tib si cov khoom siv ntshiab thiab nws cov hlau nplaum. Cov txheej txheem no tau tswj nruj me ntsis los ntawm GOST 14838-78. Hom vuam ntawm cov hlau yog ua raws li GOST 7871-75. Cov hlau nplaum hauv qab no tau siv hauv kev tsim khoom: AMg6, AMg5, AMg3, AK5 thiab AMts . Raws li GOST 14838-78, txias kab hlau (AD1 thiab B65) tab tom tsim.
Nws yog ib txwm coj los hais txog cov hlau phom sij AMts, AMG5, AMG3, AMG6, lawv muaj kev tiv thaiv kev txhim kho corrosion, thiab tseem ua tau zoo txuas thiab qiv lawv tus kheej rau txhua yam kev ua. Raws li GOSTs, txhuas hlau tau teev tseg raws li hauv qab no:
- AT - khoom;
- APT - ib nrab khoom;
- AM - muag muag;
- ATp nrog lub zog ntxiv.
Aluminium hlau tuaj yeem raug hu ua cov khoom siv ntau yam uas siv tau uas yuav luag txhua qhov txhia chaw. Thaum yuav cov khoom lag luam zoo uas tau tsim raws li GOST, cov neeg siv khoom tuaj yeem ua kom ntseeg tau tias ua haujlwm tau zoo.
